2008 Chevrolet Cobalt stability control problems

I was driving on the freeway when I changed lanes and lost control of my vehicle. My anti-lock braking system did not work as it was supposed to; my traction control did not work as it was suppose to, which resulted in me losing control of my vehicle and hitting another vehicle. A month earlier, I took my vehicle to rancho motor company to have a recall part on my vehicle fixed. They noticed that my ABS and traction control lights were on. They ran a diagnostics test on the vehicle.

Purchased this vehicle off a used car lot feb/2015 within a month of use the transmission fluid lines broke. Got back on the road, several months later the check engine light comes on and the power steering sensor as well. The car immediately started to become harder to handle. I'm scared that it will cut out on my wife and infant.
